After enduring last summer’s destructive drought, farmers, ranchers and officials across the parched Western states had hoped that plentiful winter snows would replenish the ground and refill their rivers, breaking the grip of one of the worst dry spells in American history. No such luck.

Lakes are half full and mountain snows are thin, omens of another summer of drought and wildfire. Complicating matters, many of the worst-hit states have even less water on hand than a year ago, raising the specter of shortages and rationing that could inflict another year of losses on struggling farms.
